什么？经常开发后台管理系统？需要生成左侧的菜单或者对一些数据进行分类？每次新项目都要从老项目里去复制对应的 代码？然后再微调？不不不，hierarchy-builder(层级关系生成器)可以让你更轻松的生成想要的数据结构。
hierarchy-builder 是一个php实现的非递归高性能的用于将二维数组转换为无限极分类、树状结构数组的生成器
特性
- 快速安装
- 灵活高效
安装
composer require ajiho/hierarchy-builder
用法
$data = [ ['id' => 8, 'name' => '白云区', 'pid' => 6], ['id' => 2, 'name' => '广东省', 'pid' => 1], ['id' => 1, 'name' => '中国', 'pid' => 0], ['id' => 9, 'name' => '美国', 'pid' => 0], ['id' => 6, 'name' => '广州市', 'pid' => 2], ['id' => 7, 'name' => '海珠区', 'pid' => 6], ['id' => 4, 'name' => '龙岗区', 'pid' => 3], ['id' => 10, 'name' => '加利福尼亚州', 'pid' => 9], ['id' => 5, 'name' => '南山区', 'pid' => 3], ['id' => 11, 'name' => '洛杉矶市', 'pid' => 10], ['id' => 3, 'name' => '深圳市', 'pid' => 2], ]; $builder = (new HierarchyBuilder($data)); //或者 $builder = HierarchyBuilder::create($data); //如果您的关系字段默认不是id和pid $builder->setIdField('id'); $builder->setPidField('pid'); //也可以指定生成的层级关系字段和表示子集的字段 $builder->setLevelField('level'); $builder->setSonField('children'); $results = $builder->getCateList($pid = 0, $level = 0); $results = $builder->getTreeList($pid = 0); $results = $builder->getParents($id, $pid = 0, $include_self = true) //链式调用 $results = HierarchyBuilder::create($data)->setIdField('id')->setPidField('pid')->getCateList();
生成无限极分类列表
$results = HierarchyBuilder::create($data)->getCateList(); //结果如下 $results = [ ['id' => 1, 'name' => '中国', 'pid' => 0, 'level' => 0], ['id' => 2, 'name' => '广东省', 'pid' => 1, 'level' => 1], ['id' => 6, 'name' => '广州市', 'pid' => 2, 'level' => 2], ['id' => 8, 'name' => '白云区', 'pid' => 6, 'level' => 3], ['id' => 7, 'name' => '海珠区', 'pid' => 6, 'level' => 3], ['id' => 3, 'name' => '深圳市', 'pid' => 2, 'level' => 2], ['id' => 4, 'name' => '龙岗区', 'pid' => 3, 'level' => 3], ['id' => 5, 'name' => '南山区', 'pid' => 3, 'level' => 3], ['id' => 9, 'name' => '美国', 'pid' => 0, 'level' => 0], ['id' => 10, 'name' => '加利福尼亚州', 'pid' => 9, 'level' => 1], ['id' => 11, 'name' => '洛杉矶市', 'pid' => 10, 'level' => 2], ]; // 获取id为2下面所有的子集分类列表 $results2 = HierarchyBuilder::create($data)->getCateList(2); //结果如下 $results2 = [ ['id' => 6, 'name' => '广州市', 'pid' => 2, 'level' => 0], ['id' => 8, 'name' => '白云区', 'pid' => 6, 'level' => 1], ['id' => 7, 'name' => '海珠区', 'pid' => 6, 'level' => 2], ['id' => 3, 'name' => '深圳市', 'pid' => 2, 'level' => 0], ['id' => 4, 'name' => '龙岗区', 'pid' => 3, 'level' => 1], ['id' => 5, 'name' => '南山区', 'pid' => 3, 'level' => 2], ]; // 设定level的层级从1开始自增 $results3 = HierarchyBuilder::create($data)->getCateList(6,1); //结果如下 $results3 = [ ['id' => 8, 'name' => '白云区', 'pid' => 6, 'level' => 1], ['id' => 7, 'name' => '海珠区', 'pid' => 6, 'level' => 1], ];
生成父子级树状结构列表
$results = HierarchyBuilder::create($data)->getTreeList(); //结果如下 $results = [ ['id' => 1, 'name' => '中国', 'pid' => 0, 'children' => [ [ 'id' => 2, 'name' => '广东省', 'pid' => 1, 'children' => [ [ 'id' => 6, 'name' => '广州市', 'pid' => 2, 'children' => [ [ 'id' => 8, 'name' => '白云区', 'pid' => 6, 'children' => [] ], [ 'id' => 7, 'name' => '海珠区', 'pid' => 6, 'children' => [] ], ] ], [ 'id' => 3, 'name' => '深圳市', 'pid' => 2, 'children' => [ [ 'id' => 4, 'name' => '龙岗区', 'pid' => 3, 'children' => [] ], [ 'id' => 5, 'name' => '南山区', 'pid' => 3, 'children' => [] ], ] ], ] ], ] ], ['id' => 9, 'name' => '美国', 'pid' => 0, 'children' => [ [ 'id' => 10, 'name' => '加利福尼亚州', 'pid' => 9, 'children' => [ [ 'id' => 11, 'name' => '洛杉矶市', 'pid' => 10, 'children' => [] ], ] ], ] ], ]; //更改子节点的字段为son $results2 = HierarchyBuilder::create($data)->setSonField('son')->getTreeList(); //结果如下 $results2 = [ ['id' => 1, 'name' => '中国', 'pid' => 0, 'son' => [ [ 'id' => 2, 'name' => '广东省', 'pid' => 1, 'son' => [ [ 'id' => 6, 'name' => '广州市', 'pid' => 2, 'son' => [ [ 'id' => 8, 'name' => '白云区', 'pid' => 6, 'son' => [] ], [ 'id' => 7, 'name' => '海珠区', 'pid' => 6, 'son' => [] ], ] ], [ 'id' => 3, 'name' => '深圳市', 'pid' => 2, 'son' => [ [ 'id' => 4, 'name' => '龙岗区', 'pid' => 3, 'son' => [] ], [ 'id' => 5, 'name' => '南山区', 'pid' => 3, 'son' => [] ], ] ], ] ], ] ], ['id' => 9, 'name' => '美国', 'pid' => 0, 'son' => [ [ 'id' => 10, 'name' => '加利福尼亚州', 'pid' => 9, 'son' => [ [ 'id' => 11, 'name' => '洛杉矶市', 'pid' => 10, 'son' => [] ], ] ], ] ] ];
获取指定id节点的父级列表
$results = HierarchyBuilder::create($data)->getParents(8); //结果如下 $results = [ ['id' => 8, 'name' => '白云区', 'pid' => 6] ['id' => 6, 'name' => '广州市', 'pid' => 2], ['id' => 2, 'name' => '广东省', 'pid' => 1], ['id' => 1, 'name' => '中国', 'pid' => 0], ]; //搜索到pid为1停止 $results2 = HierarchyBuilder::create($data)->getParents(8,1); //结果如下 $results2 = [ ['id' => 8, 'name' => '白云区', 'pid' => 6] ['id' => 6, 'name' => '广州市', 'pid' => 2], ['id' => 2, 'name' => '广东省', 'pid' => 1] ]; //搜索结果不包含当前传入的id节点本身 $results3 = HierarchyBuilder::create($data)->getParents(8,1,false); //结果如下 $results3 = [ ['id' => 6, 'name' => '广州市', 'pid' => 2], ['id' => 2, 'name' => '广东省', 'pid' => 1] ];
